fBe it `known'that ALJAMES DJ MCCLEL LAND, Jr., a citizen of the United States, and resident of Mount Vernon, in the county of Westchester and State of New York,l have invented anew and useful-Improvement in Ccks-or'Faucets, of which the following is a specification. v 1 l y .My'inventlon relatesto a cock or faucet :and is particularlywell adaptedfor use in turning as or other fluid on andoff where it enters a p uilding, the objectfbeing'to provide means for preventing the. permanent locking of thefaucetwhen, for any cause, the fluid 'is #temporarily cut off.

A further object is to provide a construc-v tion which will permit the insertion and Withdrawal of a key when the cock or faucet in -its open or Shu-t positions.

Avstillfurther object is to provide for removing the end of a broken key from the lock without dismemberingthe lock.

.In the accompanying drawings, Figure 1 is a plan View showing the guard cap partially "broken away,fFig. 2 is Ia view in side elevavtion,'l`ig. 3 is a central section in the plane' of the line-AfA Vof Fig. 1,v showing .the turn plug-'andlock turned into open position to permit the flow of Huid through it,'Fig. 4 is a similar section showing the cock turned in acut-off position and locked, and Fig. 5 is a central section in the plane of. the line B-B of Fig. 1,j.showing the key in position in its socket.

The casin is denoted by '1. It is yprovided as usualwit a conduit 2 for the passage of fluid through it'and this conduit is interrupted by the turn plug 3 through which there is a hole 4 which may be brought into and out of register with the conduit 2 to permit the l flow of fluid. throughthe plug or shut it off from passing through.-

The turn plug 8 is connected with the barrel 5 of the lock by'me'ans of dowel pins 6 and 7 to cause theplug to rotate together with Vthe barrel of the lock and the said lock is-rotatably mounted within asleeve 8 by means of a set, screw 8* in the sleeve, the oint of "which screw-'enters Ya circumferentia lgroove 5* in thebarrel 5. This. arrangement will permit the barrel to rotate within the sleeve, the barrel at the 'same time being held agamst removal from the sleeve. The sleeve is made fastwithin the casing 1 by means of countersunk screws 9 and 10 having their outer ends "covered by plugs 11 and12, respectively.

Thebarrel 5 carries severalv tumblers, in the present instance four, denoted by 13, 14, 15 and 16, seated to reciprocate in sockets in the barrel in a direction at right angles to the axis of the barrel. their the barrel is turned 'to open the cool` these tuinblers are held advanced within the key slot 17 in the barrel by means of a spring 18 seated in a chamber 19 in one side of the inner wall of the sleeve 8. When the barreliis'turned to close the cock,'these several vtumblers are brought in position to ress against a corresponding number of' ocking plungers denoted,jrespectively, by 20, 21,22, and 23, seated in sockets in the sleeve 8 and normally pressed forward into locking position by springs 24 seated in sockets in the Wall ol the casing 1. Thecoperation of locking and unlocking is simply to turn the barrel 5 from the position shown in Fig. 3, where the plug is in position to open the conduit 2 around.

'- turn plug can only be turned in a direction tov l open the conduit'2 by the insertion of the proper key-25 as shown. in Fig. 5, whichwill crowdthe tumblers back against the'plungers forcing the latter into their sockets and permitting the barrel S to be rotated together with the turn plug to open the conduit. When the plug has been opened, the tumblers are opposite thespringlS, thus permitting the withdrawal ofQthe keyby reason of the tumblers being forced against the tension of the spring into the chamber 19.

I provide an adjustable stop for preventing the permanent locking of the barrel and turn plug when the turning off of the iiuid, such as gas, is4 temporary only, as in a matter of exigency in case of ire or in the event the house is to be left unoccupied for a short period, thus doing away 'with the 'necessity of calling for the authorities to come and .unlock the faucet and tlriswithout in any manner disturbing the permanent lock# ing of the faucet in case such a locking should ,be required. The stop 28 at one end 'of the rotary movement. ofthe barrel 5 is variable sol that it may be set to prevent the barrel '5 from being turned far enough to'perrmt the locking plungers to enter the'barrel and, at

the' same time, far Ienoughto make a complete'closure of the conduit 2. w

The full open position of the' barrel is determined bythe engagement of a pin 26 on thebarrel with 'epm-27 on the sleeve 8. The full closednon-locking position of .the barrel 5` and the yfull closed ocking position of the barrel are determined by the said stop 28,1

which, in the present instance, is a screw -With its head set eccentric to its stem so that it may be thrown from the position shown in dotted'linea-Fcig. 1, tothe position shown in full lines, Fig. 1, by giving 1t a half turn.

.Whenit is in the' position shown in full lines, Fig. 1, the in 26 will enga e it before the barrel 5 has geen .turned su ciently far to the locking plunger-s 20, 21, 22, 23,

to enter sockets inv the barrelbut Vwhen the. stgp 28 is turned in the position shown in dotted ilines, Fig. 1, vthe barrel 5 may be turned into the position shown indotted lines, Fig. 1, before it enga es the said stop 28 vand in thisv osition the ocking lplungers dll enter the liarrel and permanently lock the turn plug closed. l 'f l v The foregoing construction, then, provides for the Atem orary shutting off of the fluid Without the ocking of the plug closed,r byrsimply giving the stop 28 the half turn-I into the position shown in full lines, Fig. 1,3 and then rotating the barrel 5 untiltllie pin 26 engagesiti When the eXigency is over or the family returns and wishes the fluid turned on again,

the barrel' 5 may be rotated back to its posi-y tion shown in full lines, Fig; 1, with the cock open without calling upon the company to come and unlock it.

A guard cap 29 is held on the outer end of thevbarrel`5 by means of a pivotal screw 30 to prevent foreign matter entering the key socket andthevsaid cap maybe turned to one L "sidewheneverit isdesired to insert the key.

Provision is made for punching a broken key out of the key socket byA providing thel turn plug with a tubular passage 31 extendlng from the end of the plug across the o n- `in therein and opening into the key soc et.

y hen, for any cause, the key is broken ofi' 1n its socket, ai Wire may be inserted within the tube 31 and by pushing it against the end of the key, the latter may be pushed out of i 15s-'socket lwithout dismembering the faucet.

W'hat I claim iszv l l. The combination with a cock orfaucet comprising a turn plug and a lock for locking the plug in position to close the faucet, of a variable stop for arresting the turn plug in af' nonlocking closed adjustment or in a locking closed adjustment.

2. The combination with a cock or faucet 3. W 11e combination with a cock'or faucet` comprising a -turn plug and a lock connected osition and after the therewith, the turn plug being provided with a tubular passage leading through its end y"to i thekey socket for the insertion of a key removing device. i `In testimony, that-Il claim the foregoing asmy invention, I have s ned my nameln' presence of two witnesses, t is eighteenth day of June, 1907.
